GREEN-API WhatsApp Skill

Use this skill when the user wants to send or receive WhatsApp messages, manage contacts, groups, or WhatsApp instances via GREEN-API.

Connection

Before using any tools, connect an instance with whatsapp_connect by providing instance_id and api_token (from console.green-api.com). This validates credentials and stores them for the session.

Call whatsapp_disconnect when done.
